At present, the three major diseases that endanger the lives of the elderly are stroke, cancer and heart disease. Besides cancer, stroke and heart disease are all related to temperature. Cold will promote the occurrence of stroke and heart disease, and also have a great impact on the respiratory system. It can reduce mucosal permeability, capillary contraction, immune substance secretion and ciliary activity frequency, all of which reduce respiratory resistance. Therefore, in the cold season, the tracheitis of the elderly is easy to recur, the incidence of colds increases, and it is also easy to get pneumonia. The death of the elderly due to respiratory diseases is more prominent in the cold season. Because the elderly can't adapt to the change of the weather, we need to pay attention to the influence of the weather on health, especially to keep warm in winter, which is very important for the health and longevity of the elderly.
In order to improve the defense ability of the elderly against weather changes, physical exercise is a positive way. Ran, a centenarian, believes that the tonic for longevity is sunshine and wind and rain. Regular exercise can prevent the decline of physique and organ function, improve circulatory function, improve metabolism and body temperature regulation, and thus better adapt to weather changes. Old people who exercise regularly have much stronger tolerance for cold than those who don't exercise.
In order to strengthen our endurance to the cold, we must insist on outdoor sports in winter. Exercise items can be based on their original habits, such as walking, boxing, qigong, doing exercises, jogging and so on. The amount of exercise can be slightly larger than that in summer, but at the same time, we must ensure enough calories and nutrition. Some old people who have not used to outdoor sports or are weak should gradually adapt to it and gradually increase the time for outdoor activities. You should make full preparations before exercising. Warm your limbs first to prevent your hands and feet from freezing. Of course, elderly people with chronic respiratory diseases (such as chronic tracheitis and bronchiectasis) should not do outdoor exercise in the early morning during the onset period. Old people exercise outdoors. If they are sweating, they can slow down or have a rest. Don't take off your clothes at once, even if the temperature is high.
In order to better adapt to outdoor activities in winter, elderly people who have no exercise habits in the past can also start cold-resistant exercise in summer. The exercise method is very simple, that is, washing your face or taking a bath with cold water. Generally speaking, it is harmless to take a bath with cold water when the temperature is above 25℃, but if the temperature is below 25℃, it must be carried out according to the physical condition. If the body reacts well, it can still be done at the temperature of 22℃-25℃ or at room temperature. When the temperature or room temperature drops below 22℃, you should stop taking a bath with cold water and just wash your face with cold water. Therefore, after 2-3 summers of cold water exercise, it will naturally enhance the cold resistance of outdoor activities in winter.
